SURGICAL INSTRUMENT.

Specification of Letters Patent.

Patented Nov. 20, 1906.

Application filed October 16, 1905. Serial No. 282,954.

'10 (0 whom it may concern:

Be it known that I, ERNEST J. OSGOOD, a citizen of the United States, residin at Oakland, in the county of Alameda and State of California, have invented new and useful Improvements in Surgical Instruments, of which the following is a specification.

This invention relates to surgical instruments, being designed especially for use in caponizing fo wls, and has for its objects to produce a comparatively simple and inexpensive device of this character which may be conveniently manipulated. and readily brought into proper engagement with the fowls testicle and one whereby the testicle may be removed without breakage and at the same time with the infliction of a minimum amount of pain to the fowl.

With these and other objects in view the invention comprises the novel features of construction and combination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a perspective view of an instrument embodying my invention. Fig. 2 is a bottom' plan view of the same. Fig. 3 is a front end elevation. Fig. 4 is a detail perspective view of the spoon end of the instrument and looking toward the inner face thereof.-

Referring to the drawings, 1 designates the stem or shank of the instrument, provided at one end with a sharpened cutting-point or spear 2 and at its other end with a testicleengaging portion or spoon 3, disposed at substantially right angles to the handle 1, as seen more clearly in Figs. 1 and 4. The engaging end 3 of the instrument is slit or incised centrally and longitudinally, as at 4,

said incision, which extends a suitable distance into the handle 1, serving to divide the spoon into a pair or relatively movable portions or sections 5, while the shank at its spoon end is flattened and has the longitudinal side edges of its flattened portion divergently inclined relatively from the shank toward the spoon, as at 6, there being formed at the bottom of the spoon and at its juncture with the flattened portion of the shank a substantially semicircular bowl 7.

Slidably disposed upon the shank 1 is a compressing member or slide 8, provided at its rear end with a split sleeve or collar 9, arranged to embrace the shank, and at its forward end with a pair of inturned portions or fingers 10, arranged at opposite sides of and for engagement with the flattened portion 11 of the shank, there being formed on the latter at a point adjacent its rear end a stop portion or lug 12, with which the collar 9 engages to limit the rearward movement of the slide 8.

In practice the peritoneum at the back of the fowl and adjacent the testicle is opened by means of the cutting portion 2, after which the spoon portion 3 of the instrument is inserted beneath the testicle, with the spermatic cord entered into the slit or incision 4, the slide 8 being thereafter moved forwardly on the shank 1, whereupon the compressing members 10 act upon the inclined edges 6 of the flattened portion 11 for compressing the sections 5 of the spoon and clamping the cord into the slit 4. The instrument is then raised and twisted for severing the cord and detaching the testicle therefrom, it being noted that the testicle will during removal lie snugly in the bowl 7. I

It may be mentioned that in the ordinary operation of caponizing the testicle is engaged by an instrument and sufficient strain or tension exerted thereon for rupturing the spermatic cord, this operation, aside from inflicting unnecessary pain to the fowl, resulting in many instances in the testicle being broken, it being a well-known fact that in cases where the testicle breaks and any particle thereof remains attached to the cord the organ will redevelop to such an extent that the fowl will grow a comb, crow, and possess other characteristics of a mature bird and its market value be consequently destroyed.

By the use of my improved instrument as above described the entire testicle is positively and effectually removed, thereby overcoming the previous objections and at the same time minimizing the pain inflicted upon the fowl.

From the foregoing it is apparent that I produce a simple device admirably adapted for the attainment of the ends in view and one whereby the testicle may be readily engaged and its removal in its. entirety effected, it being understood that in attaining these ends minor changes in the details herein set forth will be resorted to without departing from the spirit of the invention.

Having thus described my invention, what 2 Y saaeos flattened end of the instrument and com prising a pair of relatively movable sections shaped at their juncture with the stem to provide a bowl, said instrument having a space between said sections for the reception otthespermatic cord and a compressing i member slidably disposed uponthe stem and having portions to act upon the inclined i edges for compressing the spoon-sections [5 relatively into clamping engagement with the cord.

In testimony whereof I afiix my signature 1n presence of two witnesses.

ERNEST J OSGOOD.
